Someone realized this a long time ago, and the Linux kernel is already being audited and tested, with regression tests, etc (see the Linux Testing Project). OpenSSH is also generally well regarded because of the same scrutiny.
Someone else made the comment that security can't be an afterthought, so PHP will probably never be auditable, and most people agree it should be dropped in favor of more robust technologies anyway.
It's somewhat understandable; OpenSSL is a bit of a mess, and the two most recent occurrences have made me seriously think about learning more crypto in order to write a replacement, ala DJB (cf sendmail/qmail, bind/tinydns). Of course, while I think I wouldn't make any buffer overflow errors (I've got tools and training for that), I'm fairly certain I wouldn't get the crypto right the first time, and probably not the second either . . .
That being said, I too get annoyed at a few misguided POVs:
1) "Open source sucks!" - This bug would probably never been found, and even less likely would it have been fixed had OpenSSL been closed source.
2) "C sucks!" - OpenSSL would not be so widely used if it was written in another less portable, less efficient language, and besides, bad code can be written in any language.
I'd be fascinated to see what the results would be if the problem was tackled by somebody who was both capable of getting the crypto right, and willing to use DJB's substdio or any of the various equivalents.
Google+ appears to do the same thing with C-PgUp and C-PgDown; if I had wanted those keys to stop working properly, I would have used some ass-backwards browser like IE. If I've got a Google+ post open and I'm scrolling brisking through tabs, it's like hitting a brick wall.
If someone donates money to support a bill to make it illegal for straight people to marry, then the comparison might be justified. Until then, equating a private, in-born sexual preference (or opinions of such) with attempting to enshrine bigotry in the law is really stretching things.
It's been said before and I'll say it again: some things aren't worth your full reading attention. Heck, even if they were, you don't have enough time to read everything.
That being said, I am a little worried that people (at least myself) aren't getting as "deep" into topics as they might have used to. I try to solve this by (very carefully!) picking books that I can slowly digest, over multiple readings. If nothing else, just reading them at the inspectional and superficial levels can help me decide whether I need to go back for more.
